But yes, truly this is about me buying 4E stuff and not getting to use as much of it as anticipated. And now I feel somewhat irritated that my spent money on all these shiny hardbacks is going to waste because it feels that the most commonly played RPG will now be something else shortly.* And I question the need for the shift to the new. It generates business for companies but it doesn't seem to help the player base at all.
* Is it really that wrong, as a player/DM, to develop for and build knowledge around the most commonly played set of rules? Sometimes minor personal preference in rule-sets pales beside who you get to play with.
